在日历之间转换 [英] Convert between calendars

问题描述

如何在日历之间进行转换？这是我有的：

How to convert between calendars? Here is what I have:

UmAlQuraCalendar hijri = new UmAlQuraCalendar();
GregorianCalendar cal = new GregorianCalendar();

DateTime hijriDate = new DateTime(1434, 11, 23, hijri);
DateTime gregorianDate = ...; //

我需要一个对应的 gregorianDate 到 hijriDate 。

推荐答案

code> DateTime 始终在当前日历中。所以如果当前日历是格里高利的话，那么已经在格里高利了。

It seems that the Date saved in DateTime is always in the current calendar. So if the current calendar is Gregorian hijriDate is already in Gregorian.

var hijriDate = new DateTime(1434, 11, 23, hijri);
//Console writeline will show 2013-09-29 00:00:00

如果您当前的日历是 UmAlQuraCalendar 您应该可以使用以下方式提取公历日期：

If your current calendar is UmAlQuraCalendar you should be able to extract a Gregorian date using:

var hijri = new UmAlQuraCalendar();
var cal = new GregorianCalendar();

var hijriDate = new DateTime(1434, 11, 23, hijri);
var y = cal.GetYear(hijriDate), 
var m = cal.GetMonth(hijriDate), 
var d = cal.GetDayOfMonth(hijriDate)
